Hey hajharil,
If I understand correctly, you are trying to update iOS on your iPad over the air, but it is stuck at Download and Install. There are a few different reasons why this could be happening, but another thing you could do is use the first article to troubleshoot. If you are still not able to, the second article explains how you can update using iTunes.
You need an Internet connection to update iOS. The time it takes to download the update varies according to the size of the update and your Internet speed. You can use your device normally while downloading the iOS update, and iOS will notify you when you can install it. To improve the speed of the download, avoid downloading other content or use a Wi-Fi network if you can.
